The Information Service is a fundamental component in a grid environment. It has to meet a lot of requirements such as access to static and dynamic information related to grid resources, efficient and secure access to dynamic data, decentralized main

This paper presents the message passing interface (MPI)-based parallelization of the three-dimensional hydrodynamic model SHYFEM (System of HydrodYnamic Finite Element Modules). The original sequential version of the code was parallelized in order to
The last release of the NEMO v4.2 ocean model includes many modifications that have a significant impact on the model performance. The goal of the work is to assess NEMO performance obtained due to the optimizations carried out during the last four y

One of the main bottlenecks for NEMO scalability is the time spent performing communications. Two complementary strategies are here proposed to reduce the communication frequency and the communication time: the MPI3 neighbourhood collective communica

In the roadmap of modern parallel architectures development, the computing power of a node grows much more quickly than main memory performance (capacity, bandwidth). This leads to an even much higher gap between computing and memory resources. An ef

This work describes the introduction of a second level of parallelism based on the OpenMP shared memory paradigm to NEMO, one of the most widely used ocean models in the European climate community. Although the existing parallelisation scheme in NEMO

The present work aims at evaluating the scalability performance of a high-resolution global ocean biogeochemistry model (PELAGOS025) on massive parallel architectures and the benefits in terms of the time-to-solution reduction. PELAGOS025 is an on-li

The ocean engine of NEMO is a primitive equation model adapted to regional and global ocean circulation problems. It is intended to be a flexible tool for studying the ocean and its interactions with the others components of the earth climate system
